How can irony be lost where there is no irony?
Perhaps the irony was too subtle for you? Try this instead:
"The truth is starting to come out about just where these folks came from. They were protesting in the street because ..... because they were told to. It turns out talk radio media was stoking the fire. In fact, they went a step further ... even telling them when and where to protest ... what to wear and how to do it. It was an all-out propaganda war."
God forbid, they even had a WEB SITE with information on WHEN AND WHERE to protest (nothing like that happens here at Free Republic, move along, folks, there's nothing to see here ; )
